Apparatus of tape dispenser to hold the tail of tape

ABSTRACT

A tape dispenser comprises a handle. A base plate is disposed at an end of the handle, which has a tape mount pivoted at back side thereof and a seat member disposed at front side thereof. The seat member provides a cylinder at front side thereof for free rotating, a cutter at front end thereof above the cylinder and a plate at front end thereof between the cylinder and the cutter. An attracting piece is disposed on the plate of the seat member, which can produce static electricity on the surface thereof. The attracting piece has an adhesive layer at back side thereof, which can make the attracting piece secured at the plate and can prevent the static electricity on the attracting piece spreading to the seat member. Thus, the tail of the tape can be attracted by the attracting piece.

FIELD OF THE INVENTION

[0001] The present invention relates to a packing tool, and moreparticularly to a tape dispenser, which can hold the tail of tape on thedispenser.

BACKGROUND OF THE INVENTION

[0002]FIG. 1 shows a conventional tape dispenser 90, which is applied tothe workplace, such as the warehouse department of a factory, the postoffice or delivery company where need to pack boxes and the like a greatquantity and frequently. Please refer to FIG. 1, the tape dispenser 90disposes a tape roll thereon. The tape 91 is drawn out and runs along acylinder 92 with a pressing piece 93 pressing the tape 91. Then the tape91 is drawn to the cutter 94. In operating, please refer to FIG. 2,operator holds the handle of the tape dispenser 90 and attaches the tailof the tape 91 on the box 95 first. Thus, operator can move thedispenser 90 to draw the tape 91 out to make it attached on the box 95.After packed the box 95, the operator can turn the dispenser 90 an angleto make the cutter 94 cutting the tape 91 off. However, when the cutter94 cuts the tape 91 off, there is nothing to hold the tail of the tape91 that will make the tape tail waving freely. Operator needs to holdsthe tail of the tape 91 to make it attached on another box 95 first, andthen he/she can draw the dispenser 90 to make the tape 91 attached onthe box.

[0003] An earlier invention to fix the problem is to provide a metalseat member, which is the element labeled 96 in FIG. 1 and FIG. 2. Themetal seat member 96 can produce static electricity on the surface tomake the plate, which is the element labeled 97 in FIG. 1 and FIG. 2,between the cylinder 92 and the cutter 94 attracting the tail of thetape 91. Thus, the plate 97 will attract the tail of the tape 91 theafter the tape 91 being cut. But I found the seat member 96 can notconcentrate the static electricity on the plate 97 only, the staticelectricity will spread to the entire seat member 96. So sometime theplate 96 is fail to attract the tape.

SUMMARY OF THE INVENTION

[0004] The primary object of the present invention is to provide a tapedispenser, which can hold the tail of tape fixedly after the tape beingcut off.

[0005] According to the objective of the present invention, a tapedispenser comprises a handle. A base plate is disposed at an end of thehandle, which has a tape mount pivoted at back side thereof and a seatmember disposed at front side thereof The seat member provides acylinder for free rotating and a cutter. An attracting piece is disposedon the seat member between the cylinder and the cutter, which canproduce static electricity on the surface thereof. Thus, the tail of thetape can be attracted by the attracting piece.

DETAIL DESCRIPTION OF THE INVENTION

[0012] Please refer to FIGS. from FIG. 3 to FIG. 5, the preferembodiment of the present invention provides a tape dispenser 10, whichcomprises a handle 12, a base plate 14 secured at the topside of thehandle 12, a tape mount 16 pivoted at the back side of the base plate 14and a seat member 18 secured at front side of the base plate 14. Theseat member 18 pivots a cylinder 22 at front side thereof and secures acutter 24 above the cylinder 22. The elements of the tape dispenser 10are as same as the prior art, so I will not describe the detail.

[0013] Please refer to FIG. 4 and FIG. 5, the seat member 18 of the tapedispenser 10 has a rectangular pate 19 at front end thereof between thecylinder 22 and the cutter 24, which attaches an attracting piece 32thereon. The attracting piece 32 is made of polyvinyl chloride (PVC),which has apertures 33 thereon. The area of the attracting piece 32 issubstantial equal to the plate 19. The attracting piece 32 has anadhesive layer 34 at back side thereof for attaching the attractingpiece 32 on the plate 19 securedly. In this prefer embodiment, theadhesive layer 34 of the attracting piece 32 is a twin adhesive piece,which is made of foam and has thickness of substantial 0.2 mm. There areanother way to attach the attracting piece 32 on the plate 19 of theseat member 18, such as provides liquid adhesive on the back side of theattracting piece 19 to make the attracting piece 32 attached on theplate 19 directly, after the adhesive is solidified, it will form theadhesive layer 19 too, or just secures the attracting piece 32 on theplate 19 by hot pressing.

[0014] The attracting piece 32 is to provide the capacity of staticelectricity attraction, so the attracting piece 32 also can be chosenfrom another macromolecular material or metal piece, such as aluminumpiece, which can produce static electricity easier and can hold theelectric charges on the surface. In operating, the tape will rub againstthe attracting piece 32 rapidly to make the attracting piece 32producing static electricity on the surface. This is we call it as“frictional electricity” in physics.

[0015] As we know, the foam and the adhesive are insulations, so theadhesive layer 34 of the attracting piece 32 has another function ofisolating the attracting piece 32 from the plate 19 to make the staticelectricity can not spread to the seat member 18. Thus, the staticelectricity is concentrated at the attracting piece 32 only to provide alarger static electricity attraction.

[0016] In operating, please refer to FIG. 6, user operates the tapedispenser 10 of the present invention to make the tape 40 sealing a box50 and drives the cutter 24 cutting the tape 40, the tail of the tape 40will be attracted by the attracting piece 32 by means of the staticelectricity produced on the attracting piece 32. Thus, user can continuenext packing work without having to hold the tail of the tape 40. Theefficiency of the packing work will increase greatly.

[0017] In the prefer embodiment as described above, I provide apertures33 on the attracting piece 32 are to facilitate the attracting piece 32attached on the plate 19 of the seat member 18 fixedly.

[0018] The advantages of the present invention are:

[0019] 1. It only needs to attach the attracting piece on the seatmember, there is no further element is added in the tape dispenser 10 ofthe present invention. It has lower cost than the prior art.

[0020] 2. The adhesive layer further has a function of isolating theattracting piece from the seat member to prevent the static electricityspreading to the seat member. Thus, the attracting piece can securelyhold the tail of the tape for a longer time, because of the staticelectricity is concentrated at the surface of the attracting piece.
